Transformer Oil: 
25# transformer oil is from Karamay Refinery. The oil indicator can reach the oil level for 500KV transformers. Factory test of test transformer should use new transformer oil supplying with transformers and perform oil inspection before or after factory test. Oil inspection report should be provided when the transformer delivered filled with oil. Quality of transformer oil should meet the requirements of SH0040-91, GB2536-90, GB7595-87, SD187-86, Class II A of IEC-296 standards. Components PCB are prohibited in the oil. When doing acceptance test on-site, the oil performance should satisfy the following requirements: DGA analysis of total hydrocarbons less than 10 mg/L, the breakdown voltage of the oil should not be less than 65kV/2.5mm, dielectric loss (90°C) is not more than 0.3%, water content is not more than 10mg/L, the gas content is not more than 1%.
